Manhattanhenge is set to stun spectators again Friday evening, as long as clear skies prevail.
Rain and clouds obstructed the first chance to see the sunset align with the Manhattan street grid this year, but New Yorkers have another opportunity Friday and Saturday.

When does Manhattanhenge happen?
The famous sunset happens on four days each year, twice when the full sun aligns and twice when half the sun aligns. The dates fall around Memorial Day and in mid-July.
Here are the dates and times for 2019, according to the American Museum of Natural History:
Wednesday, May 29: Half the sun aligns at 8:13 p.m.
Thursday, May 30: Full sun aligns at 8:12 p.m.
Friday, July 12: Full sun aligns at 8:20 p.m.
Saturday, July 13: Half the sun aligns at 8:21 p.m.
Where are the best places to watch Manhattanhenge?
To see the sunset, your best bet is to go to clear cross streets, such as 14th, 23rd, 34th, 42nd and 57th streets. Another great spot to view is from Hunters Point Parks in Long Island City.
The AMNH recommends standing on the east side, but keeping a clear view of the west so you can still see New Jersey. Plan to get to your viewing spot at least a half-hour before the sun is expected to align.
How did Manhattanhenge get its name?
Manhattanhenge was named because of its similarity to when the sunrise aligns with Stonehenge in England.
When does the sunrise align with the grid?
An early-morning version of Manhattanhenge happens around mid-January and late November or early December each year, according to the museum. The best spots to see the sunrise are on 34th and 42nd streets, looking east.
